Disassembly report: zhengtuo 65W 2c1a Gan charger Pro

Zendure recently launched a new 65W gallium nitride charger - superport S3 pro. The charger continues the Roman column design and is equipped with foldable ins and popular 2c1a interface. At first glance, many people will think it is no different, but after comparison, it is still very different.

Although zhengtuo 65W gallium nitride charger superport S3 has been made very small, the pro version is smaller. As a multi port charger, the power density even reaches 0.97w/cm ³, It's very small and portable. Secondly, it supports 45W + 20W dual port charging strategy, which can meet the fast charging requirements of MacBook and iPhone 12 at the same time. Next, the charging head network will disassemble this new product in detail to see the specific design materials.

1、 Appearance of zhengtuo 65W Gan Pro

Zhengtuo superport S3 Pro gallium nitride charger continues the Roman column appearance design, which is white and very compact. Zendure brand is installed on the fuselage.

The input end is equipped with foldable GB pin, which is easy to carry and will not scratch other devices in the bag.

The charger parameters are marked on the input housing

C1+A:45W+18W(63W Max)

C2+A:5V3A(15W Max)

Three port output:

C1+C2+A:45W+15W(60W Max)

Manufacturing: Guangzhou Jianghai Technology Co., Ltd

Manufacturer: Zhaowen Electronics (Shenzhen) Co., Ltd

The product has passed 3C certification.

The top of the fuselage is equipped with 2c1a interface. The black rubber core of the usb-c port is not exposed to copper, and the green rubber core of the usb-a port. In addition, the logo of the pen, tablet and mobile phone is printed beside the C port.

The measured length of charger body is 65.97mm by vernier caliper. The width is 29.96mm.

The thickness is 33.93mm. The volume of charger is 67.06cm ³, So the power density is about 0.97w/cm ³, The best multi port Gan charger. Compared with apple 61W charger, the volume advantage is very obvious.

Compared with the superport S3 version, the pro version is smaller.

The output protocol of usb-c1 port is detected by using chargerlab power-z kt002. The display supports apple 2.4a, Samsung 5v2a, DCP protocol, qc2.0 / 3.0, AFC, FCP, SCP, pe2.0, pd3.0, PPS fast charging protocol, and the compatibility is very good.

In addition, the PDO message shows that the C1 port also has five fixed voltage ranges of 5v3a, 9v3a, 12v3a, 15v3a, 20v3.25a, and a PPS voltage range of 3.3-11v5a.

The protocol of C2 port measured by kt002 is the same as that of C1 port.

In addition, the PDO message is also the same, that is, the output performance of the two C ports is completely the same, which supports power blind insertion and is more convenient to use.

Usb-a port supports apple 2.4a, qc2.0/3.0, AFC, FCP, SCP, pe2.0 and other protocols, and has good compatibility.

2、 Disassembly of zhengtuo 65W Gan Pro

The fuselage shell is disassembled, the pins are sealed and fixed with screws, and the wires are connected with the PCB board for power on.

The top of PCBA module is equipped with heat sink, the high-voltage side is also pasted with adhesive tape insulation, and the back of PCB motherboard and secondary step-down panel is pasted with thermal pad to help heat conduction. Use vernier caliper to measure PCB motherboard length 60.42mm. The width is 29.69mm. Front view of PCB board, front, middle and back three section layout of components, clear hierarchy, three USB bus bases at the output end are welded on the small board.

At the back of the PCB, the optocoupler and two y-capacitors are across the primary stage. The primary side is equipped with chip fuse, main control chip and Gan power switch tube, and the secondary side is equipped with synchronous rectifier controller and rectifier tube.

The input end is provided with a small board, and there are four high-voltage filter electrolytic capacitors.

Close up of SMD fuse, rated current 5A.

Summary of dismantling charging head net

Zhengtuo's new 65W gallium nitride charger superport S3 Pro continues the Roman column ID design in appearance, but its volume is smaller, and its performance also keeps up with the current 20W hot market, supporting the dual fast charging demand of iPhone 12 and notebook. In addition, the charger supports mainstream fast charging protocols such as QC, AFC, FCP, SCP, pe2.0, PD and PPS. The overall compatibility is very good, which can meet the fast charging needs of most devices on the market. The dual C port supports power blind insertion, and is easy to use.
Apple Charger Cable
Through the disassembly of the charging head net, we know that as a columnar charger, the classic three-stage layout design is adopted in the interior, with distinct layers, and small boards are set at the input and output ends, making full use of the internal space. Secondly, the charger uses switching power supply and two-way DC-DC architecture, which is also very typical.

The switching power supply is composed of the main controller of Anson and nv6115 gallium nitride power chip, and the synchronous rectifier controller of MPS and Weizhao rectifier. The scheme is mature and reliable. The two-way secondary step-down circuit at the output end adopts Zhirong sw3516h + Ruijun ruh4040m2, and the overall material is mainstream.
